CYLINDER-LOCK.

vented certain new and useful improvement-sv in Cylinder-Locks, a specication. y

Our invention relates to cylinder locks, and has for its object the production of'a lock belonging to the class having series of pins abutting end to end and adapted for arrangement by means of a key in such manner that the cylinder may be turned and the parts unlocked, our invention consisting in the special construction the various essential parts.`

VV e laccomplish the stated object by fashioning and associating the parts as illustrated in the accompanying drawings, of which Figure l represents a vertical section lengthwise through the lock. Fig. 2 is a cross-section of our invention applied to a door. A portion of the door is also'shown sectionally. Fig. 3 is a face view of the surface or side of the lock which is to be placed against a door. Y

Like letters of reference are employed to designate the same parts throughout;

Considering the drawings, the casing of the lock is marked .A,.and the bolt B. The bolt has a special form? It extends from the of which the following is front of the lock upwardly as shown and is provided with a surface or side b resting in movable contact with the inside of the top of the casing. The bolt extends rearwardly and then downwardly substantially at right angles with the surface b, and the foot of the bolt has a surface b resting movably against the inside of the lower portion of the casing. The two surfaces or sides of the bolt mentioned are parallel one to the other, and as the bolt moves faces against the parallel surfaces of the casing. It will be here'noted that the particular shape 0f the bolt leaves the middle portion of the casing unoccupied for the reception of other parts to be described. y

The bolt B is yieldingly held in locking position, that is to say, with its head projecting beyond the casing, by the spring C, one end of which is attached to the post D projecting from the bolt laterally, and -the remaining end of the spring is secured to the post E projecting from the inside of the casvspcification or Letters Patent. Application led December 10,

and arrangement of it is guided by those sury Patented oet. e, 1908. 1907. seria No. 405,914.

. ing. Thus, when the bolt is moved to the rig t, it encounters the force of the spring C which returns it into the position shown in the drawings when the unlocking effort is withdrawn. The bolt is directly operated by the plate F, one end of which is secured upon the inner end of thecylinder G. One

of the screws by which the plate F is tached to the cylinder is shown in Fig. 2. As the cylinder turns the free end of the plate is brought edgewise against the bolt, moving it to the right as will readily be understood from the drawings. rlhe cylinder G'. occupies a corresponding orice in the housing H, and upper and lower extensions J and K are formed integrally with the middle portion H. Those extensions are diametrically opposite each other and each is provided with a row of pin holes j and 7c, in which are arranged the pins L and springs M, the springs being beneath the pin in each hole and tending to force the pin beyond the mouth of the hole. The cylinder G is provided with a number of corresponding holes in which are the relatively shorter pins N, without springs beneath them.

N ow considering Fig. 2, there will be noted the escutcheon O asv an entrance for the key Q. The key passes entirely through the door P, and the passage p therefor, it will be seen, is relatively very small, being in fact sufficient only for the introduction and rotation stated that the mechanism of the lock is wholly contained in the casing, no part of the cylinder or other element being inserted into the door.

The cylinder housing H, and its extensions J and K are usually integral parts of the plate R, shown in Fig. 3, and this plate lies against the door when our invention is in position.

The key Q is a split key, and has two sinuate edges. When the key is inserted as illustrated in Fig. 2, the abutting ends of the pins L and N coincide with the surface of the cylinder which may be turned by the key. A middle portion g of the cylinder lenters the split or recess in the end of the It is thought to be now clearly made out that by reason of the special form and arrangement of the bolt B, room is made within the casing for the two extensions of the cylinder housing form and arrangement of that housing be- H, and thus the specialcomes practicable. Further, as a result of the construction and disposition of parts as described, all the lock mechanism is included within the casing and the whole rendered as compact as it is believed can be done.

Having now described the construction and arrangement constituting our invention, what we claim isl. n a cylinder' lock, the combination with a casing, the opposite sides of the casing having parallel interior surfaces, a bolt having a surface in Contact with one ot said parallel surfaces of the casing, the said bolt having a rear portion extending across the interior of the casing and the end of said portion of the bolt being arranged in contact with the other parallel surface oi: the casing, a revoluble cylinder and a cylinder housing having corresponding spring pins, and a device actuated by the cylinder and arranged to act against the said rear portion of the bolt to move the bolt, substantially as described.

2. In a cylinder lock, the combination with a casing, the opposite sides of the casing having` parallel interior surfaces, a cylinder l and a cylinder housing provided with corresponding sinking pins whereby the cylinder may be locked and unlocked, the said housing being arranged transversely within lthe casing, and a bolt having a horizontal portion passing above the said housing and provided with a surface arranged inovably against one oli the said parallel interior snraces of the casing, the said bolt having` a vertical rear portion integral at its upper end with the said horizontal portion, thc lower end ot the said vertical rear portion of the bolt being arranged inovably against the remaining parallel interior surface o1 the casing, and a plate aitachcd to the cylin der and arranged to act against the `said rear portion. of the bolt to niove the bolt, substantially as described.

n testimony whereoi we allix our signatures in presence of two witnesses.
